That ones for the 2500's only and is a replacement for the stock stabilizers that come installed on those from the factory. It's a replacement part, not an add-on part.Sorry, wasn't clear with my question. The bilstein 5100 from the link above. Connects to the pitman arm (non-u-bracket) and how is it best secured from there? It doesn't come with an L-shape bracket to drill into the frame does it?
